I hate to break it to you but the pharmacist dispensing your insulin is quite involved in your treatment. He is one of the lines of defense should your physician order an incorrect dosage. He is also a resource for adverse effects, drug interactions and antidotes. He is a behind the scenes VIP in your care.
If a pharmacist was ethically opposed to insulin he would not be employed in an institution which required it or another pharmacist without objections would be available to dispense.
I’m surprised at the number of people championing their own rights who are more than willing to violate the rights of others.
